Abstract
The present invention provides an antistatic composition comprising a binder, a cyclic phosphazene, and a salt that complexes with the cyclic phosphazene. The cyclic phosphazene has the general formula ##STR1## wherein x is 3 or 4.
Claims17
An antistatic composition comprising a binder, 1 to 50 weight percent on a dry weight basis of a cyclic phosphazene, and 1 to 20 weight percent on a dry weight basis of a salt that complexes with the cyclic phosphazene to produce an antistatic composition, wherein said cyclic phosphazene has the general formula ##STR15## wherein the x is 3 or 4,
- R.sub.1 and R.sub.5 each independently represents the formula --(R.sub.2 --O).sub.n --R.sub.3 wherein n is 0 to 50, and n is 2 or more for at least half of the total substituents, R.sub.2 is randomly alkyl of from 2 to 4 carbon atoms, having from 2 to 4 carbon atoms in the straight chain between oxygen atoms, and R.sub.3 is alkyl, alkenyl, alkynyl, haloalkyl, haloalkenyl, haloalkynyl, phenyl, substituted aromatic, amine, or thio of from 1 to 18 carbon atoms,
- W, and X, each independently represents ##STR16## wherein R.sub.6, R.sub.7, and R.sub.8 each independently represents H, alkyl, alkenyl, alkynyl, haloalkyl, haloalkenyl, haloalkynyl, phenyl, substituted aromatic, amine, or thio of from 1 to 18 carbon atoms.
